Special Feature in Cura

I am not clear about some of the feature in Cura and hope to get some tutorial or guide for this. Here is the list of features: 
1. The two features in the picture below

2. ADAPTIVE LAYERS

3. MOULD FEATURE

4. WIRE PRINTING

5. SPIRAL MODE

The top feature is a per model setting. You can adjust some basic values per model like speed, support, etc.

The bottom one is a support blocker. I sometimes use this to prevent small holes from being supported.

2. Adaptive layers calculates how layer heights can be optimized. If a model has no small details it will print thicker layer heights to decrease print time.

3. Not quite sure on this one..

4. Not sure here either.

5. Basically a "Vase" mode. The model is printed in a spiral without any infill.

I would recommend downloading the "Settings Guide" from Cura's marketplace(this should be in the top right somewhere. If you're unsure about a setting you can right click on it and settings guide should appear in the drop down menu.

Hi Tankenland and nighthawk 🙂

1. The top button allows you to override settings for that particular model as nighthawk said. So if you want to print two things at once on the same build plate but with different overrides, you use that button. More details here: https://support.ultimaker.com/hc/en-us/articles/360012031399-How-to-adjust-print-settings-per-model-in-Ultimaker-Cura

The bottom button is a support blocker. It allows you to position a shape onto areas where you don't want supports to be automatically generated (like holes or internal parts of models where it would be impossible to remove supports).

2. Adaptive layers is a way to get a compromise between speed and quality. Instead of printing the whole object at a single fixed layer height, the slicer automatically adjust the layer height depending on the angle of the walls in that part of the print. For example, if you're printing a sphere, the top and the bottom of the sphere are printed in very fine layer height (0.08mm for instance) so it doesn't look too much like a staircase. The middle parts of the sphere (where the angle of the walls is almost vertical) are printed at coarse layer height (say 0.25 or 0.3 mm) to save time. The end result is the total print time is about the same as for printing with a medium layer height (like 0.2mm) but you'll get much more quality in the areas where it's needed the most.

3. Mould feature is a unique feature of cura that turns your model into a mould. So if say you wanted to make a d.ink model out of resin or chocolate, you'd import the d.ink stl file as usual, turn on mold mode, and cura will make a negative of your model (where it's basically a block with a cutout or cavity in the shape of the model). More info here: https://support.ultimaker.com/hc/en-us/articles/360012614279-Special-modes-settings

4. Wire printing is a kind of "fun" way to make models where the printer just prints the outline of the model by going up and down, forming v-shaped lattices (a lot like the trusswork of a metal bridge or tower crane). It doesn't have much practical use except for artwork (like a more extreme form of Voronoi sculptures) and there's a good chance it will fail on many models, but you can always give it a try. Here's what it looks like: https://www.youtube.com/watch?v=CDB3MaS86TY

5. It's the same as vase mode. It means your model's walls are printed in a continuous spiral (aka helix or corkscrew) from bottom to top instead of layer by layer. The thickness of the line of the spiral is still equal to the layer height, but instead of stopping at each layer (making a z-seam) and then moving up and starting a new layer, it angles each layer slightly so that the z-axis is constantly rising slowly while it's printing the wall. To give you an idea of the z-axis speed, it goes up by one layer height for each revolution of the XY axes (assuming a round vase). So if LH is 0.2mm and it takes the printer 10 seconds to print a "layer" (actually one revolution of the vase perimeter) the z axis will rise at a speed of 0.2mm per 10 seconds or 0.02mm/sec. The thickness of the wall in vase mode is equal to your extrusion width setting.

Spiral/vase mode requires some settings to be changed. Your top layers become zero (because vases are open on the top), number of walls/perimeters becomes one (because the spiral can only print one wall at a time), and only the outermost wall of your model is printed (no internal walls or details).

Hope this helps! 🙂

Regards,
Luke
